METHOD FOR DETECTING CONCENTRATION OF PARTICLES AND DEVICE THEREFOR

摘要

Provided are a magnetic particle producing part 2 having magnetic and counterpart members 14 and 16 in a path L2 of a particle-includable liquid S, at least one of the members 14 and 16 being moved to press the other member in the liquid S, the magnetic member 14 being worn by particles in the liquid S to produce magnetic particles; a magnetic particle measuring part 3 positioned in the path L2 same as in the producing part 2 to measure the magnetic particle concentration in the liquid S; and a control part 4 converting the concentration of the magnetic particles detected by the measuring part 3 into a concentration of particles in the liquid on the basis of a calibration line representing a correlation preliminarily measured between the concentrations of the magnetic particles and of the particles in the liquid S to detect the concentration in the liquid S.
